You don't need more then 2 leaf2Hub connections for optimal connection. Having anything more will not at all affect your search results or download speeds positively.

And if you're having connection and internet problems, try stepping down your settings to no more than 8 peer2peer ones and 400 Hub2leaf ones. This should solve your problem. Probably your router is not capable of maintaining that much simultaneous connections (probably it's the many UDP packets that do kill it and cause the connection losses).
